20130062 | Date of diagnosis--Heme & Lymphoid Neoplasms: Should the diagnosis date be coded to the date of the flow cytometry on the peripheral blood or the date of the bone marrow biopsy for a diagnosis of chronic lymphocytic leukemia/low grade B-cell lymphoma? See Discussion. | Is a flow cytometry on peripheral blood alone diagnostic of a hematopoietic malignancy (CLL)? If not, when the diagnosis is verified by a subsequent histologic diagnosis (bone marrow biopsy) would the diagnosis date be the date of the peripheral blood flow cytometry or the date of the bone marrow biopsy? The Class of Case depends on this diagnosis date. | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Code the diagnosis date to the date of the peripheral blood flow cytometry because this is a procedure used to diagnose CLL. Per both the Abstractor Notes and the Definitive Diagnostic Methods sections in the Heme DB, CLL is diagnosed by flow cytometry (immunophenotyping).

20100044 | Primary site--Heme & Lymphoid Neoplasms: Should the primary site be coded to C499 [Blood vessels, NOS] for a case of intravascular large B cell lymphoma, Asian variant [9712/3] found in the bone marrow and liver? See Discussion. | Patient has biopsy proven intravascular large B cell lymphoma, Asian variant, (9712/3) in bone marrow and liver. The Hematopoietic Database does not give a primary site code. Should the primary site be coded C49.9 because, by definition, this lymphoma arises in the blood vessels? | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Code primary site to C499 [blood vessels]. The definition in the Heme DB does specify that this type of extranodal large B-cell lymphoma is characterized by lymphoma cells within the lumina of blood vessels with the exception of larger arteries and veins. The reason no primary site is specified is that Western variant can originate in the skin or CNS.

20110084 | Histology--Heme & Lymphoid Neoplasms: Is histology coded to 9684/3 [malignant lymphoma, diffuse large B-cell, immunoblastic NOS] for a biopsy that reveals "diffuse large B-cell lymphoma, immunoblastic variant"? | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Code histology to 9680/3 [diffuse large B-cell lymphoma]. Code 9684/3 [malignant lymphoma, diffuse large B-cell, immunoblastic NOS] is obsolete for cases diagnosed 2010 and later per the Heme DB.
Under the Definitions section in the Heme DB, it states that this is a lymphoma with diffuse proliferation of large neoplastic B lymphoid cells with nuclear size exceeding macrophage nuclei, more than twice size of normal lymphocytes. Normal architecture of node or extranodal tissue replaced in diffuse pattern. Morphologic variants: centroblastic, immunoblastic, plasmablastic, T-cell/histiocyte-rich, anaplastic.

20130069 | Reportability--Heme & Lymphoid Neoplasms: Is chronic myeloproliferative neoplasm reportable? See Discussion. | The Heme DB indicates myeloproliferative neoplasm is reportable, but does not indicate whether chronic myeloproliferative neoplasm is. Does the word "chronic" make this non-reportable? | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Chronic myeloproliferative neoplasm is reportable. The preferred term is myelodysplastic/myeloproliferative neoplasm, unclassifiable (MPN). Chronic myeloproliferative neoplasm is listed in the Heme DB under the Alternate Names section for this neoplasm.
The term chronic does not affect the reportability of this neoplasm. The newer terms are myeloproliferative neoplasm or myeloproliferative disorder and chronic is not used in most diagnoses.

20130139 | Histology--Heme & Lymphoid Neoplasms: How is the histology coded when the original slides are reviewed at a later date and the revised diagnosis changes the histology? See Discussion. | Diffuse large B-cell lymphoma [9680/3] diagnosed in 5/2010 and treated with chemotherapy. In 11/2012 a bone marrow biopsy revealed small lymphocytic lymphoma (CLL/SLL) [9823/3].
The 2010 slides were reviewed and showed, "a large cell lymphoid proliferation, many of the cells which appear to be prolymphocytes. There are background smaller lymphocytes that are consistent with CLL/SLL. In retrospect, the lymph node most likely represented a prolymphocytic conversion in SLL."
The medical oncologist is calling this a recurrent lymphoma. Should the original 5/2010 diagnosis be changed to 9823/3 [CLL/SLL]? Is this documented in the Heme Manual? |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Change the histology of the original 2010 diagnosis to 9823/3 [chronic lymphocytic leukemia/small lymphocytic lymphoma] based on the review of the 2010 slides. The 2010 diagnosis was revised based on the review of slides and the histology should be changed accordingly. The closest example of this is located in the SEER Manual, Changing Information on the Abstract, instruction 3, example 4.
Histology code 9670/3 [SLL] is obsolete for cases diagnosed 2010 and later. All diagnoses of CLL/SLL, CLL, and SLL are now coded to histology code 9823/3 [CLL/SLL].

20130014 | Reportability--Heme & Lymphoid Neoplasms: Is Castleman disease reportable when diagnosed 2010 and later? | When checking Castleman disease in the Hematopoietic Database, the result is a reportable histology code 9738/3. However, per an online search, Castleman disease is a very rare disorder characterized by non-cancerous growths (tumors). | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Castleman disease, NOS, is not reportable for cases diagnosed 2010 and later. However, when Castleman disease is diagnosed in connection with large B-cell lymphoma [9738/3], it is reportable.

20100087 | Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned for one patient with history of marginal zone lymphoma initially diagnosed in 1994, followed by a 2010 diagnosis of large B-cell lymphoma and another patient with both B-cell chronic lymphocytic leukemia/small cell lymphoma (CLL/SLL) and diffuse large B-cell (DLBCL) in 2009? See Discussion. | Case 1 - Patient has a history of marginal zone lymphoma diagnosed in 1994 with recurrences in 2007 and 2009. The patient now presents for a bone marrow biopsy in May 2010 and is found to have large B-cell lymphoma, transformation. The first primary, marginal zone lymphoma, falls under the 2009 rules and the second primary, large B-cell lymphoma, falls under the 2010 and forward rules?
Case 2 - Patient was diagnosed with B-cell CLL/SLL and a DLBCL in 2009. If the 2009 rules only apply, these are a single primary. If the patient is admitted and treated in 2010 are the rules still based on the diagnosis date? |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Case 1: Accession two primaries per Rule M10 when a neoplasm is originally diagnosed as a chronic neoplasm AND there is a second diagnosis of an acute neoplasm more than 21 days after the chronic diagnosis. The histology for the first primary is 9699/3 [marginal zone lymphoma] represents a chronic neoplasm and the second primary is 9680/3 [diffuse large B-cell lymphoma] is an acute neoplasm which was diagnosed more than 21 days after the first primary.
Case 2: Do not use the Heme DB and Manual rules for this case. Both diagnoses were made prior to 2010. The Heme DB and Manual are only effective for cases diagnosed 1/1/2010 and forward. Use the ICD-O-3 Hematopoietic Primaries Table to determine the number of primaries for this case. Per the Table, a second diagnosis of DLBCL [9680/3] following a diagnosis of CLL/SLL [9823/3] is one primary.

20100089 | Primary site--Heme & Lymphoid Neoplasms: How is primary site coded when lymphoma is initially found in both lymph nodes and bone marrow, the pathology report is unavailable, and the physician only states that both areas are involved? See Discussion. | For many consultations and/or class 2 cases, the pathology report is not available to help determine the primary site. Should the primary site be automatically coded to C421 over C77_ when both are involved? The Abstractor Notes state the primary site can be either bone marrow or lymph nodes. The physician states only that both are involved. | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Because both the bone marrow and LN are involved, code the primary site to C779 [lymph nodes, NOS] per Rule PH22. You are to code specific nodes if a specific region is specified; however, if no region is specified, code to lymph node, NOS [C779]). When you are having problems coding primary site, go to Module 7 Primary Site Rules for Lymphomas Only. See Rule PH26. It states that you code the primary site to bone marrow when ONLY the bone marrow is involved.
